Dataset preview is not available (I think for all Hugging Face datasets)
## Dataset viewer issue for '*french_book_reviews*'

**Link:** https://huggingface.co/datasets/Abirate/french_book_reviews

**short description of the issue**
For my dataset, the dataset preview is no longer functional (it used to work: The dataset had been added the day before and it was fine...)  
And, after looking over the datasets, I discovered that this issue affects all Hugging Face datasets (as of yesterday, December 23, 2021, around 10 p.m. (CET)).  
**Am I the one who added this dataset** :  Yes   

**Note**: here a screenshot showing the issue
